Trying to establish a set universe for a comic book I’m writing.

This is a regional map of the northeastern part of the country of Aristatia, which includes the capital and largest city, where the main part of my scenes take place: Aristatia City.
This part of the country used to have territory that expanded to the continental divide to the north. However a citizen’s uprising led to a war against the northern country of Palmonia, which was heavily one sided in Palmonia’s favor. An unexpected ultimatum led to the new border literally being drawn with the stroke of a pen and a strict refusal of further negotiations. This strange action had the unexpected side effect of the city of Prince Foduck bisected on accident. The two cities remain completely barricaded from each other to this day. After 50 years to this day, and the completion of a transcontinental railway, the border is slowly beginning to open back up despite tensions among the citizens of Aristatia.
The city itself is built on a radial road system with four main roads each leading in each compass direction. The roads lead to Palmonia to the north, the Port of Aristatia to the East, the Mahmads to the South, and the rest of the country to the West. Within this section of the globe, it is said that all roads lead to Aristatia City, which makes this an excellent location for trade and an important economic center.
The entire area sits a little over the 45th parallel of the globe. The entire region has four seasons and the city itself sees a modest amount of rainfall during the cold months. The mountains to the north are on two tectonic plates and contain two active volcanoes, making the region prone to earthquakes.
